User profile disks - 2012 R2 - Can they be made to apply to some terminal user logins not all.

Hello,

I have a group of terminal servers. If I the administrator log into Terminal Server (TS) 1. The user profile disk works great. If I log into TS 1 and 2, the user profile disk works on TS1 but I get a temporary profile on TS2. This figures as two users can't open the same VHDX. Unless like in Cluster, Virtual Hard Disk Sharing, is enabled, but as far as I can tell, that isn't an option.

So, is there a way to enable User Profile Disks by Active Directory group? Or identify some users that won't use User Profile Disks?

Or am I missing something and I should be able to open the same profile disk on two different logins.

Thanks again,

Robert
